[email protected]Contact
One accountable address for each operational task.
These role-based mailboxes are routed to the DisputeTracker operator. Use the narrowest address so registry, incident, and integration requests remain separate.
Payment operations
MPP or x402 incidents, settlement investigation, receipt validation, and production availability.
[email protected]API support
OpenAPI, discovery, integration questions, response schemas, and buyer implementation help.
[email protected]Include enough context
For a payment investigation, include the protocol, network, endpoint, UTC timestamp, public transaction hash or receipt reference, and the HTTP status. Never email a private key, seed phrase, full authorization header, facilitator secret, or unredacted production credential.
